我有3个域：
example.com
sub1.example.com
sub2.example.com
所有这些都指向一个服务器和一个文件夹。我想保护sub1.example.com和sub2.example.com不使用密码访问根文件夹，但不是主域，它应该可以在没有密码的情况下访问根文件夹。我的意思是：
example.com => allowed
sub1.example.com => blocked with password
sub2.example.com => blocked with password
sub1.example.com/* => allowed
sub2.example.com/* => allowed
*是一个可以是任何内容的文件夹。我试着在网上和这里找到它，但找不到，我该怎么做？
